Over the last month or so my EA has been stopping every now and then (prob about once or twice a week). I will just be driving along normally with no problems, then ill pull up at an intersection or something where i have to get off the throttle and it starts coughing and spluttering. Usually I can keep it going, but if I cant then it seems the only way to get it going is to disconnect the fuel line from the rail, start it and let the fuel burn up, then slip the fuel line back on before she starves! Major pain in the butt...especially when youre stopped in the middle of the Princes Highway!
The strange thing is that it only does it sometimes, then itll be right for a while...
My initial thought is bung injectors...Anyone got any ideas or advice???
however sometimes it will idle at about 1300 - 1500 rpm for about 10 - 15 secs before dropping back to normal.
seems to develop a missfire on the days that its stopping too. have replaced the plugs with new motorcrafts but no change.
fine with a/c on, and fine with power steering full lock.
just on another note, i recently discovered I had a power steering fluid leak, but could not work out what the hell was going on as the fluid seemed to be coming out near the battery! upon closer inspection, the fluid was coming out the power steering switch (i think that adjusts the idle speed to compensate for when you turn the wheels) and being pumped up thru the wiring loom! Replaced the switch and now everything is beaut.
Could have problem to the ISC, which stands for idle stepper motor, located above the trottle body and has 2 wires plugged onto it. noramlly when this plays up car wont idle or will stall when a/c on or p/s in full lock.
Try resetting the ecu, by doing this
leave the car running for about 5 mins in drive, with the handbrake on in a safe spot where it can run away. this re-learns the ecu, especially handy after reconnecting battery.
Could also be distributor hall effect (inside dissy cap) or module (mounted on side of dissy) playing up intermittently. bit hard to check when it only does it sometimes.
